FRANK 1\T. YOUNG, OF PROVIDENCE, RHODE ISLAND.

BOX-FASTENER.

Application filed February 20, 1915.

To all whom it may concern,

Be it known that I, FRANK N. YOUNG, a citizen of the United States, and resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Box-Fasteners, of which the following is a specification.

This invention relates to fasteners of the class adapted to secure the box and its cover together and the object of this invention is to provide a fastener constructed of sheet metal adapted to be readily connected to the cover of the box and folded over the bottom portion of the box to secure the two together.

A further object of this invention is to provide an extending lip on the folding tongue of the fastener adapted to perforate or enter the stock at the bottom of the box.

With these and other objects in View, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claim.

In the accompanying drawings: Figure 1- is a perspective view of the box showing my improved fastening device as attaching the cover to the bottom of the box. Fig. 2- is a sectional side elevation of the box showing the fasteners as securing the cover in position on the box. Fig. 3 is a section on line 33 of Fig. 2 showing the bendable clenching members as securing the fastener to the cover portion. Fig. L- is a plan View illustrating my improved fastener as it is cut from sheet stock before being bent. Fig. 5- is a perspective view showing the two perforated fastening wings bent up into position to pierce the stock of the cover. Fig. 6- shows the fastener as bent into operative position.

Referring to the drawings 10 designates the cover portion of the box which in this particular construction is substantially the depth of the bottom portion of the box 11, itself. The body portion of this box as herein shown, is preferably constructed of what is known as corrugated board, which board has spaced apart inner and outer walls 12 and 13 with an intermediate corrugated member 14. This style of board forms a very stiff box and yet the walls are comparatively soft and yieldable, which construction of box in some cases is favored by the postal authorities for shipping goods through the mails. In order to provide a Specification of Letters Patent.

Serial No. 9,740.

simple and effective fastener for a box of this character, I cut or stamp a member from sheet stock of the form best illustrated in Fig. 4, the same being provided with a body portion 15 which has laterally extending V shaped pointed wings 16, and a tongue portion 17 whose end is provided with a bendable lip portion shaped to provide a head 18, having a cutting edge and laterally projecting shoulders 19. In securing this fastener to the box cover I first bend the wings into the position illustrated in Fig. 5, whereby they are adapted to be forced through the stock of the box cover and their extremities folded on the inner side thereof as illustrated in Fig. 3, the tongue portion extending straight downward. When the cover is placed in position on the box the tongue member is bent over the bottom of the box which would in itself secure the two members together, butin order to obtain an additional fastening effect, I bend the head member 18 inward at substantially a right angle to the plane of the tongue member and then by pressing this tongue member inward the curved cutting edge of the head pierces the outer layer of corrugated board and enters the space within. The stock through which this head has just passed closes slightly around the same and the little shoulders 19 serve somewhat like the barb of a fish hook, to prevent the tongue from being readily disengaged, thereby providing an exceptionally eflicient, strong and durable fastening device for securing the cover to the box. v

Another feature of my improved construction is that the cover portion is a little deeper than the box portion, whereby the lower edges 20 extend just beyond the bottom of the box, whereby in bending the tongue of the fastener into position over the bottom portion it is bent a little past a right angle to the side of the cover thereby giving to it a particularly strong gripping effect and preventing it from being too readily bent back by any strain which may be applied to remove the cover from the box. Then again by the use of my improved fastener, the outer surface of the box is formed almost entirely smooth as the metal of the fastener is extremely thin and when positioned almost flush with the surface of the cover.

I have shown my fastening device as beingconnected to a box formed of corrugated board, but this fastener may be applied to a box of any construction to which it is adapted to be constructed.

I claim:

The combination with a box and its cover, of a sheet metal fastener comprising a body portion provided with means by which it may be readily attached to the cover and a tongue adapted to be bent over the bottom edge of the box at an angle to said body, said tongue having its extremity provided with a bendable lip adapted to be folded at Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

an angle to the plane of said tongue, to form a head having a cutting edge shaped to pierce the body of the box, said head being 15 provided with laterally positioned shoulders to engage the stock to resist withdrawal of the tongue when in enga ed position.

In testimony whereof I ai X my signature in presence of two Witnesses.
